## Key features

- **Chat with context from tabs and tools:** On paid plans, a question asked on any page is answered using open tabs and connected tools such as Slack, Notion, Google Workspace and Microsoft Teams.
- **Morning Brief:** A daily brief lays out the calendar, inbox and key links before the workday starts. It is part of the Better Days plan.
- **Reports, decks and recaps:** Dia gathers context scattered across tools into a shareable report or a slide deck with headers and layout. These are part of the Better Days plan.
- **Meeting prep:** Before a call, Dia opens the meeting page, agenda, notes and related documents and shows a countdown to the start time.
- **Profiles, tab groups and split view:** Profiles keep work, freelance and personal tabs, logins and AI separate. Related tabs are grouped under descriptive names, and split view layouts are remembered.
- **Privacy controls:** Ad and tracker blocking are built in, memory and chat personalization can be switched off, and synced data is end-to-end encrypted. Dia for Work adds SSO and admin tools.

## Good for

- Mac users whose work is spread across Slack, Notion, Google Workspace and Teams
- People who want a daily brief and meeting prep prepared for them
- Arc users moving to the company's newer browser

## Worth knowing

- The free Better Browser plan has no AI features; chat needs Better Answers at $20 per month, and the Morning Brief and reports need Better Days at $100.
- Paid usage is metered in Tasks. When the monthly allowance runs out, AI features pause unless extra usage is bought in $20 credit blocks.
- Dia is available for macOS only; the site lists Windows as coming soon.
- Paid plans began rolling out to new Mac users on August 17. Existing users keep free access until they get at least 30 days' notice.
